SHADE FOR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 510,095, dated December 5, 1893.

Application filed July 23. 1892. Serial No. 441,011. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE F. SEAVEY, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Shades for Electric Lamps, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of an improved shade adapted for use in connection with electric lamps.

In accordance with my invention the shade, composed of metal or other suitable material is provided with a hub having a series of spring prongs to embrace snugly portions of the lamp socket, the said hub having near the base of its prongs a projection or annular rib, and at its end most remote from the points of said prongs the said hub has one or more lips, the material of the shade being clamped between said lip or lips and the said projection or rim, the lip or lips being adapted, as will be described, to pass through a notch in the shade near its center.

Figure 1, shows in elevation an electric lamp provided with a shade embodying my invention, the shade and its hub being represented in section. Fig. 2, is an upper side view of the shade and its hub. Fig. 3, is a view of the central portion of the shade with the hub removed. Fig. 4, is an enlarged perspective view of the hub; and Fig. 5, is a modification of my invention.

The lamp, composed of the bulb a and the socket a, is and may be of any usual construction common to electric lamps. The shade 1), herein represented as circular in form and as somewhat disk-shaped, may be composed of any usual or suitable material, preferably metal. This shade has at its center an opening or hole I) having a notch b at its edge. The hub for the shade consists of an annular strap of metal having a series of spring prongs c, and at or near the base of the prongs a projection or annular rim 0, and the end of the hub most remote from the free ends of the prongs is notched inwardly for a short distance and provided with one or more lips as 0 To apply the hub to the shade the hub will be placed preferably at the back of the shade, and one of the lips 0 will be passed closely against the shade, thus binding or confining the latter in place between the projection or rim 0' and the said lips. A shade so constructed may be readily applied to a lamp socket the spring prongs grasping the socket firmly, and thereafter the globe may be inserted into its socket to complete the usual connections with the electric current. These hubs may be easily and cheaply constructed and may be readily applied to the shade.

It is not intended to limit this invention to the particular shape of the projection or rib o and it is obvious that should the said rib project from the hub at points only substantially above the lips, the function and purpose would be the same as though the rib extended entirely about the hub, but the annular rib is preferable because of cheapness of construction, but any projection serving the purpose of a rib to rest against one side of the shade, the side opposite that against which the lips rest, is considered as in the scope of this invention. Forinstance, in Fig.

' 5 showing a modification of my invention a part of the hub has been struck through leaving a small projection c which serves the purpose of the annular rim with the exception that the rim affords additional stiffness to the hub.

Having described my invention, what I claim, and desire to secure by Letters Patent,

l. A lamp shade having a detachable metallic hub provided with a series of upturned spring prongs to embrace a lamp socket, a projection below said prongs and upon the exterior of the hub and against which the shade bears, and an outwardly turned lip, as described, to bear upon the under side of the shade, and a notch in the shade opening to admit the lip therethrough, substantially as described.

2. A lamp shade composed of a body hav the shade between them and said annularpro- I0 ing an opening provided with a notch, as If, jection or rib, substantially as described. combined withadetachable metallic ring-like In testimony whereof I have signed my hub havinga series of upturned spring prongs, name to this specification in the presence of 5 an outwardly extended annular projection or two subscribing witnesses.

rib below the base of said prongs, and a se- GEO. F. SEAVEY. ries of outwardly turned lips at its end below Vitnesses: said projection or rib, adapted to be passed GEO. W. GREGORY,
